CD4527BPWR

Specialty Logic Overview

The CD4527BPWR is a CMOS BCD-to-decimal rate multiplier manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and features a propagation delay of up to 8 µs. The device provides high and low level output currents of 4 mA each, with a typical operating supply current of 300 µA. It is housed in a 16-lead TSSOP package suitable for surface mount installation. The component supports an extended operating temperature range from -55°C to +125°C and has a power dissipation rating of 500 mW.

Specialty Logic Feature Summary

• Performs binary-coded decimal (BCD) to decimal conversion and frequency multiplication functions.

Specialty Logic Applications

• Digital clock circuits requiring rate multiplication.

Specialty Logic Procurement Notes

Verify the specific suffix 'G4' if lead-free compliance is required, as standard versions may differ. Confirm the TSSOP-16 package dimensions against your PCB footprint design. Ensure the input signal levels are compatible with the specified CMOS logic thresholds for reliable operation across the full voltage range.

Specialty Logic Selection Notes

Select this component when a dedicated BCD rate multiplier is needed rather than a general-purpose counter. Consider the 3V to 18V supply flexibility for varying system voltages. Evaluate the 8 µs propagation delay against timing requirements. The wide temperature range supports industrial or automotive environments where standard commercial grades are insufficient.

Specialty Logic Part Context

This part belongs to the CD4500B series of CMOS logic devices. It serves as a specialized timer and support product within Texas Instruments' portfolio. The device complements other logic families by providing specific arithmetic functionality for digital systems without requiring complex discrete implementations.

Specialty Logic Replacement Considerations

The CD4527BPWRG4 is a verified lead-free alternative within the same package and specification set. Cross-referencing with generic CMOS counters requires verifying internal logic structure differences.
